That was a mistake, as I mixed something up, probably it loaded an old version of the module ... to be on the save side the steps I used this time (in case we see something unexpected and for my later reference): $ git log --oneline 4c922df10252 (HEAD -> atomisp, origin/atomisp) media: atomisp2: get rid of ia_css_sc_param.h version dependency ... $ make -j4 clean $ make -j4 $ sudo make modules_install INSTALL_MOD_STRIP=1 $ sudo make installPlease try to build from this branch: https://git.linuxtv.org/mchehab/experimental.git/log/?h=atomisp_v2 You'll need to setup a new config var there. So, please run this before make clean. So, for building it, you will do: $ ./scripts/config -e CONFIG_VIDEO_ATOMISP_ISP2401 && make -j modules_prepare $ make -j4 clean && make -j4 $ sudo make modules_install INSTALL_MOD_STRIP=1 && sudo make install This won't change the regulator detection, but it should hopefully use the ISP2401-specific code, with seems to be needed for your device.
I've updated to the latest source (git checkout atomisp_v2 && git pull) and compiled using the instructions above. Compilation worked well, but the linker had some problems (full log attached):
...ld: drivers/staging/media/atomisp/pci/css_2401_system/hive_isp_css_2401_system_generated/ia_css_isp_states.o:(.data+0x0): multiple definition of `ia_css_kernel_init_state'; drivers/staging/media/atomisp/pci/css_2401_csi2p_system/hive_isp_css_2401_system_csi2p_generated/ia_css_isp_states.o:(.data+0x0): first defined here
...Not sure if I can help with that. Sounds like we have to remove definitions - which I might be able to do. But I would need to know where the right place is to keep the definitions. If a code generator is involved (one of the paths looks like it) it will be more difficult for me. But with some hints I'm of course willing to give it a shot. Please give me an example of a definition) and a hint in case we deal with generated code.
I changed the configuration of my mail client; a test message looked ok. Let me know if the problem persists.Ah, when replying, could you please use an emailer that won't be breaking long lines? Your emailer is currently breaking lines longer than 80 columns, with is quite annoying when checking log results ;-)
Thanks, Mauro
with kind regards Patrik
